FLOOR WAXING AND POLISHING MACHINE.

Application filed. April 10, 1916. Serial at. 90,054,.

To all whom it may concern:

Be it known that I, HERMAN H. LUEDER, a citizen of the United States,and a resident of Sioux City, in the county of Woodbury and State ofIowa, have invented certain new and useful Improvements in Floor Waxingand Polishing Machines, of which the following is a specification.

The present invention relates to means for, coating and polishing planesurfaces.

The invention has for itsprimary object the production of an improveddevice for waxing and polishing floors.

A further object of the invention is the production of a device adaptedto wax and polish floors more perfectly andrapidly, and with a minimumof labor.

Another object of the invention is the production in a device of thissort, of improved means for regulating the amount of wax delivered, andfor delivering the same uniformly.

A still further object of the invention is the production in a device ofthis sort of improved means for regulating the wax-delivering means tosuit the consistency of the wax.

Furthermore, the invention provides a floor waxer andpolisherinexpensive in construction, effectively and easily operated, andreadily adjustable.

With these and other objects in view, the invention, consisting in theconstruction, combination and novel arrangement of parts, will be fullyunderstood from the following description, reference being had to theaccompanying drawings, which form a part of this application and inwhich like characters of reference indicate corresponding partsthroughout the several views, of which,

Figure 1 is a side'elevation of a device constructed in accordance withthe invention; Fig. 2 is a plan of the same; Fig. 3 is an enlargedtransverse section of the waxcase; and Fig. 4: is an enlarged elevationof the wax-forcer adjustment.

Referring, now to the illustrations, the main frame of the embodimentchosen for illustration, comprises horizontal side members, 5, providedat their rear ends with upwardly inclined handle-bars, 6. The in-Specification of Letters Patent.

Patented @ct. 31, 1916.

termediate portions of the side members are interconnected bycross-members, 7, uponwhich is mounted an electric motor, 8, or othersuitable rotary power. The mainframe is supported upon travel-wheels, 9,mounted on the side members, 5.

The motor-shaft, 10, carries a pulley, 11, connected'by a belt, 12, witha pulley 13, fixed on the spindle, 14, of a brush, 15, disposed betweenthe front ends of the side members of the main-frame. 'The brushspindles are journaled in suitable bearings, 16, mounted on the mainframe.

A vertically-movable frame is provided to support the wax-deliveringmeans and comprises forwardly-extending arms, 17, pivoted on themotor-shaft, 10, and provided with rearwardly-inclined arms, 18, one ofwhich is extended and provided with a pawl 19, engageable with aquadrant, 20, mounted on the adjacent handle-bar, 6. The opposite arm,17, of the movable frame, is bent laterally, as at 21, and firmlysecured to the companion arm to prevent relative movement between thetwo arms. Between the arms, 17, is mounted a suitable wax case,including side walls, 22, having lateral ears, 23, firmly secured to thearms, 17 and a curved front and top wall, 24.

The case incloses a roller, 25, having spindles, 26, protruding throughthe side walls and journaled in bearings, 27, in the ends of the movableframe arms, 17 The roller, 25, is rotated by a pulley, 28, mounted onone of the spindles, 26, and connected by a belt, 29, with themotor-pulley, 11. The wax within the case is forced against the roller,by means to be presently described, and as the roller revolves in thewax and normally on the brush, it is obvious that a coat of wax willadhere'tothe roller and thus constantly wax the brush. The wax is forceddownwardly and forwardly by a concavo-convex plate, 30, the lower edgeof which is pivoted as at 30, adjacent the lower rear corners of theside walls of the case.

The presser-plate is of suflicient width to pass freely between the sidewalls of the case, and still prevent leakage of wax at the sides; and ispivoted concentric with the front wall in order that the presser platemay at all times be in contact therewith,

Will

The presser-plate is held in yieldable engagement with the wax by acompression spring, 31, secured to the presser-plate, and carried by abar, 32, the rear end of which is provided with notches, 33, engageablewith a suitable stop, 34, carried by the movable frame member, 21.

The lower edge of the front wall of the case is formed with a flange,35, the under side of which is embraced by a strip, 36, secured to theflange. by bolts, 37, which pass through the flange and transverseslots, 38, in the strip, whereby the strip may be adjusted toward orfrom the roller to regulate the quantity of wax fed from the case.Between the lower edges of the side walls of the case, and at the rearof the roller, extends a cross-member, 39, which serves to reinforce thecase and prevent leakage of the .wax at this point.

It is evident that in operation the roller delivers the wax uniformlyupon the brush, and the latter applies it upon the surface being waxed,as the machine travels. The compression on the presser-plate may also bearied at will by changing the adjustment of the slotted bar on the stop34.

On the main-frame is secured a bracket, 41, havingthereon anidler-pulley, 42, engaged by the lower lead of the'belt, 29, to tightenthe belt. By tilting the extended arm, 18 forwardly, and rearwardly, thebelt 29, will be accordingly tightened or loosened. -When sufiicient waxhas been distributed on the floor, the arm 18 is tilted rearwardly,thereby raising the roller from the brush and slackening the belt, 29,to deenergize the waxing mechanism. The operation of the brush is thencontinued to polish the floor.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,
